Getting Started with php

Our Currency Convertor API is easy to integrate with PHP applications. Below you'll find a complete example of how to use our API.


// Example of using the Unirate API with PHP
$api_key = 'YOUR_API_KEY';
$base_url = 'https://api.unirateapi.com/api';

// Function to convert currency
function convertCurrency($from, $to, $amount) {
    global $api_key, $base_url;
    
    $url = "{$base_url}/convert?api_key={$api_key}&from={$from}&to={$to}&amount={$amount}";
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, [
        'Content-Type: application/json'
    ]);
    
    $response = curl_exec($ch);
    $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);
    
    if ($http_code === 200) {
        return json_decode($response, true);
    } else {
        throw new Exception('API request failed: ' . $response);
    }
}

// Example usage
try {
    $result = convertCurrency('USD', 'EUR', 100);
    echo "Converted amount: " . $result['result'] . " " . $result['to'];
} catch (Exception $e) {
    echo "Error: " . $e->getMessage();
}

Response Example


{
    "from": "USD",
